This invention relates to a cooking appa- 7 ratus with steam hoodadapted to be heated by electricity or by gas. The invention'has forvits object to produce automatically at the correct time the controllingof the'so'urce of heat; For this purpose the water from condensation isutilized, according to the invention, which water collects under thesteamhood as soon as the temperature for cooking has set in. An alarmsignal may fof heat, i

be sounded at the controlling of the source An embodiment of theinvention is shown, by way of example, in the accompanying drawing inwhich 7 Fig 1 shows in vertical section the cock. ing apparatus and partof 'thecontroll ng .mechanism. r v Fig. 2 shows the controllingmechanism for electric heating.

Fig. 3 shows the same mechanism tor gas heating". v f The cookingapparatus is composed of the heater plate 1 which has PIOjGCtlIlg angleirons 2, 2, of a trough-shaped metal ring 3 resting upon'said angularpieces 2, and of a' trough-shaped ring 4 which has an outflow pipe 5.The ring 4 is sllghtly inclined in order that the water fromcondensation collected in the samefiows towardsthe'outflow pipe 5.Onthis outflow 5, a finger 6 is fined which is hollow and perforated andon which, by means of a band 7,. a metal ball 8 is suspended. The bandconsists of .a material which dissolves in water,or which loses itssolidity if soaked in water, for instance a strip of 'un's'ized paper asblotting paper or the like. A waterjpocket 9 1s further'arranged on theoutfiow- On a'shoulder of ring 4 rests the steam hood 10v Which coversthe two pans 33, 33 which are placed the one on the other. v

a The controlling mechanism, Fig. 2, is arranged on an insulated plate20, A1 scale beam 12 oscillatably'mounted on an axle 11 has at one end ahook 13. The other end of the beam 12 is normally pushed upward by theaction of a spring 14. The hook 13 grips then over the interruptinglever 15 oscillatable around a pin 23 and pushed upprovidedy the lattercook 28; A fixed on said cavity of ring 3 so that 126,000, and inGermany March 16, 1925.

The switch lever 15 comprises an insulated headpiece 21. The pivot pin23 forms one of the contacts the second contact being formed by aterminal 24 in which the switch lever 15 is clamped. Terminals 25, 26are nected to the contact "In the 3 the gasflows from the gas mainthrough a tubularv socket 27 to the casing of the second tubularsocket32 is clock casing and designed to conduct the gas to the heatingplate 1. On. the cook 28 an arm 29 is fixed, a blade spring 30 tendingto turn thisarm upwards. In order-Ito llllllt'thB oscillating movementof said arm or lever 29 and to regulate thereby the amount of opening ofthe gas cock, a stop screw 31 is provided. The other ele ments of themechanism are the same as, those shown in Fig. 2 and they aredesignatedby the same reference numerals- The pans 33 project over the rim ofplate 1 into the cavity of the metal ring 3, said metal ring 3intercepting liquid from boilmg over, so thatthls liquid cannot get ontothe plate 1.. he ring 3 serves further to.

protect the ring 4 against excessive heating, so that the evaporation ofthe water from condensation intheiing 4 is prevented. If necessary watermight be filled into the it evaporates and increases the heating effect.According to whether the operation of the controlling mechanism has tobe produced is previously form' of 'construction'shown in Fig.

at once ora "httlelater by the collected water from conwhich standsunderneath being electrically conso that, on the one hand, it releasesthe lookoperates said gins to sound, and, on the other hand, releases,if electric heating, the switch lever 15, and it gas heating, the cocklever 29, these levers being pushed upward by the action of the springs22 or 30. At electric heating the current is thus interrupted, and ifgas heating the cock is either entirely closed or partly closed, inaccordance with the position of the stop screw 31 If the water pocket 9is empty or only partly filled, this operation is retarded. The electriccooking plate may have several circuits, so that the electric heatingcan be switched to feeble heating inaccordance with the circuits.

As'the steam hood 10 rests upon a shoulder or ring 4 it is protectedagainst being dirtied by the water from condensation. It may be lesshigh in accordance with the hei ht of the shoulder.

l or gas heating the metal ring 3 is placed upon a gas cooker which ismounted at such height that the outflow pipe has approximately the samedistance from cup 19 asat electric heating. The lower pan stands thendirectly over the gas burner. i vvThe cooking apparatus describedpresents the further advantage that the rings .3 and lare only-looselyconnected with the electric heating plate or with the gas cooker, andthat the controlling mechanism is mounted separate from the sourceofheat, so that allfelements canbe easily cleaned. The apparatus mightbe used for baking if the ring 4; and the out flow tube 5 areomit ted,and the steam hoodis placed directly into the metal ring 3, sothat thehot gases flow under the hood and around the mate.- rial to be baked.
